3ds Max :: Texturing Faces Of Same Polygon

I have made a cube, and given a basic cube UV map. The material I want is a standard 2D map (say noise). The problem is that each face gets the same pattern of noise. I would have the same result if I had a basic bitmap as the material.

My solution has been to make a Multi-Sub material, and then use a different noise seed for each side of the cube. This works fine, but it makes it time consuming to do something like change the color of the cube (as I would have to edit 5/6 materials).

So, I am asking, is there a way to either make the UV behave as if each face was part of the same "thing" (spread one noise map over the image/stretch the bitmap). Perhaps make an object use multiple materials (or something like that), so that I can have a Multi-Sub for a greyscale noise, and then a basic color that I can change to effect all of the sides at once.
